Abstract

Various load sensors (18) support a platform (12), preferably around the geometric center, and supply signals to a controller (21). The controller (21) emits a signal to a display (22) to indicate a position of a user’s center of gravity. This display may consist of a central light (26) and an array of lights (24) which may be arranged symmetrically about the central light (26).
